Description

A die for forging high-strength wheel nuts

Technical Field

The invention relates to the technical field of nut forging dies, in particular to a die for forging high-strength nuts for wheels.

Background Art

At present, the welding nuts of automobile brake systems have complex shapes. Depending on the different uses, the precision requirements of the shapes and sizes are also different. For parts with complex shapes, there are two problems during forging: one is that the mold life is short, which is far from achieving the purpose of batch continuous production. The mold will be fatigued and damaged early, and the product cannot be mass-produced normally. The second is that the mold manufacturing cost is high. All complex shapes are electro-discharged. After electro-discharge processing, the difficulty of mold polishing increases, and the mold life is difficult to guarantee. After the mold is damaged, it needs to be replaced as a whole, which greatly wastes the manufacturing cost.

Announcement No. CN217166317U discloses a welding nut forging die. Through the provided lifting mechanism, after the use of the die is completed, when the upper die needs to be removed, the upper die can be raised in a more relaxed manner and the material in the lower die can be removed, so that the material removal problem of the device is more convenient. At the same time, the mechanism can be manually or electrically controlled according to the needs of the user, which is more flexible. Through the provided auxiliary mechanism, the connection points between the upper die and the top plate can be increased, so that the rise of the upper die can be more stable, and at the same time, it will not collide with the top plate due to reasons such as excessive rise, thereby causing damage to the upper die. However, the patent still has the following problems in actual use:

Although the welding nut forging die can utilize a lifting mechanism, when the upper die needs to be removed after the use of the die, the upper die can be raised and the material in the lower die can be removed in an easier manner. However, since the temperature of the die after forging is high, it is not convenient for operators to take it, and the die needs to be cooled. This process wastes a lot of time, which not only affects the processing efficiency of the die, but also fails to recycle the heat emitted by the die, thereby causing energy waste.

A die for forging high-strength wheel nuts is proposed to solve the above-mentioned problems.

Working principle: Before using this high-strength wheel nut forging die, it is necessary to check the overall condition of the device to make sure it can work normally. As shown in Figures 1 to 11, first, place the bottom die body 204 on the top side of the conveying base 201, and use the lifting motor 105 to drive the first sprocket transmission assembly 106 and the lifting threaded rod 107 to rotate, so that the lifting threaded sleeve 108 and the lifting sliding sleeve 110 drive the mold lifting plate 109 to move up and down. When the mold lifting plate 109 is lowered, the top die body 112 and the bottom die body 204 can be molded together, so as to achieve the desired effect. In order to facilitate the forging of welding nuts, the elastic force of the tension spring 126 can be used to pull the first clamping sliding sleeve 116 to drive the clamping support column 117 to move toward the middle of the top mold body 112. At the same time, the elastic force of the connecting spring 122 can be used to make the second clamping sliding sleeve 121 slide inside the second clamping sliding rod 120 while driving the clamping rotating rod 123 to rotate. The clamping bevel block 125 is connected to the fixed socket 134 by snapping, so as to fix the top mold body 112, improve the stability of the mold, and improve the performance of welding nut forging.

Secondly, when the top mold body 112 needs to be replaced, the mold lifting plate 109 is moved upward to drive the top mold body 112 to rise. When the clamping inclined block 125 contacts the lifting top plate 102, the inclined surface at the top of the clamping inclined block 125 is used to make the clamping support column 117 and the clamping rotating arm 118 slide relatively inside the clamping bracket 114, so that the clamping inclined block 125 is separated from the top mold body 112. When the fixing sockets 134 around the top mold body 112 are engaged with the collecting inclined block 132 at the top, the top mold body 112 can be fixed. By setting a plurality of collecting sleeves When the top mold body 112 at the bottom rises, the cylinder 128 can lift and stack the top mold body 112 from the bottom, and can automatically shrink when the top mold body 112 is stacked by utilizing the unlocking inclined groove 133 at the bottom of the collecting inclined block 132, thereby fixing the top mold body 112 and preventing the top mold body 112 from falling, thereby realizing uninterrupted replacement of the top mold body 112, placing a new top mold body 112 on the mold lifting plate 109, and pressing the top mold body 112 downward to make the clamping inclined block 125 engage with the fixing socket 134, thereby realizing the rapid installation of the top mold body 112.

Finally, the bottom mold body 204 can be moved by using the conveying chute 202 and the moving roller 203, and the second sprocket drive assembly 208 and the conveying roller 209 are driven to rotate by the conveying motor 207. The top mold body 112 can be conveyed by using the characteristics of the transmission connection between the conveying roller 209 and the conveyor belt 210. The heat emitted by the bottom mold body 204 at the bottom of the conveyor belt 210 can be used through the air vents 211 inside the conveyor belt 210 to preheat the top mold body 112 at the top of the conveyor belt 210, so as to quickly forge the welding nut, thereby improving the efficiency of the welding nut forging. When the mold lifting plate 109 is lowered to close the mold, the clamping bracket 114 is used to extrude the vertical meshing rack 218, and the vertical meshing rack 218 is used to be used. The meshing connection between the rack 218, the positioning gear 216 and the horizontal meshing rack 217 can realize the horizontal movement of the horizontal meshing rack 217. The horizontal meshing rack 217 can be used to position the bottom mold body 204 before mold closing, thereby improving the accuracy of mold closing between the bottom mold body 204 and the top mold body 112, and at the same time improving the stability of mold closing. When the top mold body 112 is separated from the bottom mold body 204, the horizontal meshing rack 217 is moved horizontally and separated from the bottom mold body 204 under the elastic force of the support spring 219, thereby facilitating the movement of the bottom mold body 204 to the bottom of the conveying chute 202 and the movable roller 203, so as to dissipate heat from the bottom mold body 204 and recycle the heat at the same time.

Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
